What is the salary ratio of Faheem, Imran, and Naveed if they earn 80,000 rupees, 70,000 rupees, and 50,000 rupees respectively?
Show answer Hide answer
Answer: B. 8:7:5
Explanation
Writing the individual earnings as a direct three-way ratio gives eighty thousand to seventy thousand to fifty thousand. Dividing each numerical term in the ratio by the common factor of ten thousand simplifies the expression. The resulting simplified integers form the reduced ratio of eight to seven to five. Mathematical ratios express the relative size of two or more values using simplified integer proportions. Simplifying a ratio involves dividing all constituent terms by their greatest common divisor. Matching units are required when comparing financial earnings or physical dimensions in ratio form.
Financial analysts use simplified ratios to compare corporate revenues and profit margins across different industries. Budget planners allocate departmental funds proportionally based on simplified salary and expense ratios. Understanding ratio simplification is essential for interpreting statistical charts and demographic data. Option A retains unsimplified numbers with trailing zeros instead of reducing the ratio completely. Option C improperly rearranges the earnings order by altering the original sequence of individuals. Option D swaps the earnings values of the first two individuals, creating an incorrect proportional match.
